It’s unclear whether the photo shows lean or a different liquid of a similar hue. It’s also unclear whether Thug actually used the IV. Nevertheless, the post sparked concerns over his apparent drug habits as well as the promotion of drug use on social media.

Lean has been criticized by many medical professionals, who say that it can have several negative effects. Some warn that it can also severely damage organs. While some rappers have glorified it, others have spoken out about its impact.

In 2008, UGK rapper Pimp C reportedly died at 33 due to “promethazine/codeine effects and other unestablished factors.” His UGK partner Bun B went on to refer to it as a “cough syrup epidemic” and established that it’s a “problem.” Last month, Wiz Khalifa also deemed lean “lame.”
